When b > a

((b x 100) / a) - 100 = (b - a) / a) x 100

how? why?

Are you fucking retarded? That's true regardless of b>a.

>>7774704
(b-a)/a=(b/a)-1

how?

If this isn't bait I think I'll kill myself. Get the fuck off this board.

We're not here to do your elementary school homework.

b - a = b - a

So it's like (b-a) from the left equals b on the right, which makes me think b-a = -1.

>>7774759
b-a equal b-1, obviously.

>>7774704
Just simplify the expression you big dum dum.
>>
>>7774774
b / (a - b) = (b - a) / a
